The message above is issued from the top-level configure, not newlib.  This is 
due to the fact that the default C library for Linux should be glibc, not 
newlib.  Building with newlib causes changes in the header files used.  To force 
the configuration to build newlib, specify --with-newlib in your configuration 
call.  Note that --with-newlib will get you a vanilla-style newlib with the base 
set of syscalls.  The newlib/sys/linux code with a more robust syscall 
arhitecture currently only supports x86.  You will have to specify an ld script 
when you compile (see the scripts in libgloss/mips).

Currently, newlib is dependent on the top-level configuration setting some key 
flags.
